GRAiN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 290,592, dated December 18, 1883.

Application filed April 8,1882. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM MAoY, a citizen of the United States, residing in Monroe township, county of Miami, and State of Ohio, have invented a new and useful Improvement in Grain-Separators, of which the following is a specification.

My invention relates to a supplementary carrier and separator combined, which is suspended from the ordinary straw-carrier of a grainseparator, and is operated by a band running on a pulley of the same, to effect a further separation of the products passing beyond the ordinary straw-carrier. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure I is a side elevation of the improved straw-carrier.. Fig. II is a top View of the extension-frame, showing its connection with the oblique frame, and omitting the endless conveyor.

Similar letters designate like parts through out the several views.

A represents the frame of a straw-carrier, which, with the rollers O and endless apron O, is identical in construction with the straw-carrier as used in connection with the grainseparater.

O is a pulley, by which motion is communicated to the endless apron. The supple. mentary carrier B, in its general features, is identical with the former, its near end being supported on arms m, which embrace the shafts of the pulleys, and the outer end is supported by the rope L, which is attached to the end of the frame, and passes through an eye on the upper end of the oblique frame, and is made fast to an eye on said frame. This device or its equivalent may be used for sustaining the outer end of the frame. The conveyor D has two belts, and the strips are attached to the same with wide intervening spaces, so that the chaff may fall freely through the same.

Near the top, and at the forward end of the frame, is secured the screen F, whose interstices are sufficient to admit of the passage of kernels of wheat.

To the bottom of the frame is secured the board E, which closes the bottom of the frame from the forward end to a point beyond the end of the screen. This catches the grain which falls through the screen, and which is conveyed by the strips of the apron to be discharged at the inner end of said board, the chaff falling through the wooden strips of the conveyer at the end of said board, and the straw being cast oft at the end of the frame. The motion is communicated to the extension-carrier through the pulleys O O and the belt J.

The operation is thus: The products of the thrasher are conveyed to the top of the inclined conveyor, where they fall onto the extensionconveyer and drop into the supplementary carrier, and the wheat drops through the screen and is discharged at the inner end of the bottom board. Beyond said board the chaff falls out, and the straw is carried off at the end of the supplementary carrier.

Having fully described myinvention, what I claim, and desire to secure by Letters Patent, 1s

The combination, with the primary carrier A, of the secondary carrier B, hinged to the primary carrier at its upper end, and supporting and adjusting cable L, passing over the upper end of carrier A, and suitable means for securing said cable.
